What's everyone working on this week (40/2022)?

New week, new Rust! What are you folks up to?

working on an esolang (created by myself):

I wrote a tiny tool creating a template file for rustfmt: rustfmt-template. It can be easily adapted to one's needs or preferences. I'm sorry for writing this in Assembly but the difference in binary size is too crazy.

I wrote a BSON-like serialization format that maps to JSON:

Main difference is that it is built so that you can treat it as a serialized tree and have a cursor walk into it without actually deserializing everything.

Currently the cursor is implemented (and uses no allocation), along with a reference implementation in Python.
I intend to implement serde serialization, and/or conversion to serde_json::Value
